'''3D Human-Computer Interaction''' (3D HCI) refers to the methods and technologies that allow users to interact with computers in a three-dimensional space. Unlike traditional 2D interactions (using a mouse, keyboard, or touch screen), 3D HCI leverages depth, volume, and spatial context to enhance user experiences and functionalities.
